OLIVER F. BOWEN, OF OBERLIN, OHIO.-

IMPROVEMENT IN ROLLER-SKATES.

Specification forming part of Letters Patent No. 153,474, dated July 28, 1574; application filed June 6, 1874.

To all whom it may concern:

Be it known that I, OLIVER F. BOWEN, of Oberlin, in the county of Lorain and State of Ohio, have invented an Improved Roller-Skate, of which the following is a specification:

This invention relates, first, to the construction and arrangement of an adjustable framework for a two-wheel skate; and, second, to.

the adjustable mechanism for fastening the skate to the shoe in a very expeditious manner; and, third, to the construction of the wheels or rollers.

To enable others to fully understand my invention, I will proceed to describe the same in detail, by the aid of the accompanying drawing, in which- Figure 1 is a top or plan view. Fig. 2 is a side elevation of my improved skate. Fig. 3 is a detached sectional view of one of the wheels or rollers.

' A, Figs. 1 and 2, is a flat bar having two cross-bars, B 0, attached, the rear one, B, permanently, and the front one, 0, adj ustably, being secured in a slot in the bar A by means of set-screws. To each end of both the cross-bars B G are attached adjustable angle-pieces b b c c, by means of set-screws passing through slots. These are to clamp the skate to the sides of the sole and heel of the shoe. To the under side of the cross-bars B O are attached pillar-blocks D E, in the lower ends of which are the bearings for the wheels F G. These pillar'blocks consist of two strips of iron, d 0, having a block of wood, (1, secured between them, the lower end of said blocks being hollowed out to form the bearings f0r.the journals of the wheels F and G. The wheels F G consist of a small shaft, f, two metal disks, g g, and a wooden wheel, h, placed between them on the shaft, and whicliis somewhat smaller in diameter than the metal disks, which form an annular groove for the rubber ring 6. The disks 9 g and h are firmly secured together by screws jj, thus clamping a part of the rubber ring in the said annular groove, firmly retaining it in place. To the front end of the barA,

which is bent upward, is affixed an adjustable toe-piece, K, and to the rear end is affixed an adjustable slotted post, Z, having in the top a cam and lever, m. In front of the rear crossbar B is placed, in a slot in the bar A, a hook, n.

These devices, together with the an gle-pieces b I) c c, are for securing the skate to the shoe, the operation of which is as follows: Having adjusted the several parts, the skate is placed on the sole of the shoe, the heel being between the cam m, which is turned down, and the hook at. Now, by turning the cam up by means of its lever, the foot is forced forward between the clamps b I) c c, and the point of the book a into the front side of the heel of the shoe. The skate is then firmly attached to the shoe, with the lever standing upright.

O O are side bars secured to the sides of the pillar-blocks D E, which help to brace them, and from them arise two arms, P P,

made in two parts and jointed at a point opposite the ankle-joint, and are provided with a strap to be buckled around the leg. These are for the purpose of .bracin g the ankle of the wearer.

This mode of fastening the skate is applicable to both the ice andthe' fioor skate.

Having described my invention, I claim- 1. In'a roller-skate, the bar A, cross-bars B C,'angle-pieces b o, pillar-blocksD E, the wheels F G, the bars 0 0, and upright ankle-support 1?, all constructed substantially as described.

2. The toe-piece K, the post I, the cam and lever on, and the hook at, in combination with the subject-matter of the above claim, as and for the purpose set forth.

3. The wheels F G, composed of the disks g g, wooden wheel h, rubber ring i, and shaft 8, all as shown and described.
